To all who)! if may (o/warn:

130 it known that I, FREDERICK VAN Damn, a subjoci of the Queen of thoNoihorlmnls, and a resident of Detroit, in the county of Wayne and Stan:of Michigan, have invented ('LIillill new and useful lmprm'ouwuts in Libhrimtiug Atl'zu'lunonts for Thread-Cuting Dies, of which rho followingis a specificalion" This lnvoul'ion relates to lubricating otlm-hmontior ihrozul cutting dies, and an ohjor-t of the invention is to pr rideon oil uziu' which is lloiuolizzbly carried by one of ii]? lmmilos of :1(lie stock, the spout of whiv'h can oxiouds longitudinally along theoutletpositioned so tho the oil or lubricant ejooiod therefrom willengage the, work or article upon which the threads are being out. i

ll: is well-known, that to insure ills livieut; operation of ilirolidcutting dies, it is uocvsszu'y to lubricate the cutting edges of (he(lios, and also the material upon which the threads are being cut. hisis commonly done through the medium of an or- (lino 11v oil mm fromwhich lard oil or similar light bodied luliricmifi is forced upon thedim but in using zmgoriiinary oil can it is Il(l'(,' f-;%l-ly lo stop orarrest the rotating mowmunt oi iho (lie and stock to apply the lubricanttlloreto If: is :m oli iout' of this invention to pr mm on oil can pmt'ulm'ly (lesi 'necl for at iavluuout i0 mu. of handles of (lie si orizvfiliil'fiby the lubricating oil 111 ho fed to i-lm (lifi and a 'olvlaoin; worlior'l 119011 during the working opesmiion of iii-3 die,eliminating the DPCOSSiiY of stopping; the opera lion of the die inapply lubricant thereto,

Other objects, of the invention will appear in the following: detaileddescription, taken in conneciion with iim forming; a, pari Of thisspocifioation and in which drawing:
